Catching up with 49ers’ final cuts Adams and McCown

Nearly a year after ex-49ers cornerback Phillip Adams suffered a gruesome ankle injury, the team’s seventh-round pick in 2010 signed Tuesday with the Seahawks, who will host San Francisco on Saturday.

Adams broke his left ankle in a 25-17 loss at St. Louis on Dec. 26, 2010. He participated in San Francisco’s training camp this summer, but acknowledged he wasn’t back at full strength. He was among the Niners’ final roster cuts on Sept. 3.

Adams played in six games this season with the Patriots, who released him on Nov. 29.

After signing with the Seahawks this week, there’s no guarantee Adams will be active on Saturday against the 49ers. The Seattle Times reported that Adams was signed in the event cornerback and special-teams standout Kennard Cox can’t play due to a hamstring injury.

* In news involving another of the 49ers’ final roster cuts, Bears quarterback Josh McCown will start on Sunday at Green Bay.

McCown, who was acquired by Chicago on Nov. 23, will replace Caleb Hanie, who has thrown nine interceptions in four starts since starter Jay Cutler broke his thumb. The Niners signed McCown on Aug. 17, but released him Sept. 3 and subsequently signed undrafted rookie Scott Tolzien to be their No. 3 quarterback.
